◆ FractionalCloudCover
Defines the fractional cloud cover [1] given by observation of total cloud amount in eights (oktas) of the sky.
For visual alignment please see reference [2].
The total degree of coverage indicates how much of the sky is covered with clouds altogether. 0 oktas means that there are no traces of clouds in the sky, 8 oktas means that the sky is completely covered with clouds and no sky blue can be recognized.
